1. What is Degree of Dissociation?

Definition: The Degree of Dissociation is the extent of generating current carrying free ions, which are dissociated from the fraction of solute at a given concentration.

Purpose: It helps chemists understand how much a weak base dissociates in solution at equilibrium.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \alpha \) — Degree of Dissociation
• \( K_b \) — Dissociation Constant of Weak Base
• \( C_0 \) — Initial Concentration (mol/m³)

Explanation: The degree of dissociation is calculated by taking the square root of the ratio between the base dissociation constant and the initial concentration.

3. Importance of Degree of Dissociation

Details: Knowing the degree of dissociation helps predict the strength of a weak base and its behavior in chemical reactions.

4. Using the Calculator

Tips: Enter the dissociation constant (Kb) and initial concentration (C0) in mol/m³. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the range for degree of dissociation?
A: For weak bases, α typically ranges between 0 and 1, where 0 means no dissociation and 1 means complete dissociation.

Q2: How does concentration affect degree of dissociation?
A: As concentration decreases, degree of dissociation increases (inverse relationship).

Q3: What are typical Kb values for weak bases?
A: Weak bases typically have Kb values between 10⁻² and 10⁻¹².

Q4: Can this formula be used for strong bases?
A: No, strong bases completely dissociate (α = 1) and don't have an equilibrium constant.

Q5: What are the limitations of this formula?
A: It assumes dilute solutions and ignores activity coefficients. For more accurate results, use more complex equations.
